DC Motor Protector

We are a supreme manufacturer, supplier and exporter of dc motor protector (sn-25). The sn-25 series is a high current motor protector which delivers the benefit of locked rotor and overload protection in a robust integrated package. the sn-25 series has been designed to offer protection for a wide range of 12 volt to 48 volt applications in a minimum package size. The sn-25 series is suitable for both intermittent and continuous rated motors. The sn-25 is also designed for manual switching operations. The sn-25 is physically small and has unique 'snap action' bimetal disc, ensuring a positive make and break switching action for enhanced contact life.
